EM Group Thick-Walled Heat Shrink Tubing with Adhesive 33/8mm Black 1m

The EM Group thick-walled heat shrink tubing with adhesive is a high-performance solution designed for robust electrical insulation and environmental protection. Featuring a 33/8mm diameter and a 4:1 shrink ratio, this tubing is engineered to provide a tight, secure fit around cables and connectors. The integrated internal adhesive lining melts during the shrinking process, creating a permanent, moisture-resistant seal that protects against corrosion, chemicals, and mechanical stress in demanding industrial environments.

Advantages

This heat shrink tubing offers exceptional durability due to its thick-walled construction, which provides superior resistance to abrasion and impact compared to standard thin-walled alternatives. The adhesive lining ensures an excellent bond to a wide range of materials, including metals and plastics, effectively preventing moisture ingress and environmental contamination. Its high shrink ratio allows for versatile application across varying cable diameters, simplifying inventory needs while maintaining consistent performance and reliability in harsh conditions.

Suitable for

• Electrical cable splicing and jointing
• Environmental sealing of cable terminations
• Protection of electrical components against moisture and chemicals
• Mechanical reinforcement of cable assemblies
• Industrial wiring systems requiring high durability

This tubing may not be suitable for applications involving extremely high-temperature environments that exceed the material's thermal rating or for installations requiring high flexibility, as the thick-walled construction is relatively rigid once shrunk. It is also not intended for use in medical or food-grade applications where specific non-toxic certifications might be required.

Key specifications

• Shrink ratio: 4:1
• Diameter before shrinking: 33 mm
• Diameter after shrinking: 8 mm
• Material: Thick-walled polyolefin with adhesive lining
• Color: Black
• Length: 1 meter

To use this tubing, cut a piece to the desired length, ensuring it extends beyond the area requiring protection. Slide the tubing over the cable or connector and apply heat evenly using a heat gun or a controlled heating tool, starting from the center and moving toward the ends. Continue heating until the tubing has fully conformed to the shape of the object and the adhesive has flowed out slightly at the edges, indicating a proper seal.

What to consider before purchase

• Verify that the 33/8mm diameter range is compatible with your specific cable or connector size
• Ensure the heat source used is capable of reaching the required activation temperature
• Check if the application environment requires resistance to specific chemicals or high mechanical loads
• Confirm that the 1-meter length is sufficient for your project requirements

Usage recommendations

For optimal results, ensure the surface of the cable or component is clean, dry, and free of oils or debris before application. Avoid overheating the tubing, as this may damage the material or compromise its structural integrity. Allow the assembly to cool completely before subjecting it to mechanical stress.
